Original application filed Iteceniber 14,1925, Serial No. 75,372.Divided and this application filed July This application is a divisionof my U. S. application, Serial No; 7 5,37 2, filed Dec. 14, 1925,patented Aug. 23, 1927, Number The invention has reference to planters,such as corn planters, which are provided with seed dropping meansdriven by the wheels of the planters instead of being actuated by acheck wire. Such mechanisms require the use of some eflicient checkcorrecting means from time to time, and the present invention aims toprovide such a-means which will be rather simple and inexpensive, yetwill be eflicient and reliable.

With the foregoing in view, the invention resides in the novel subjectmatter hereinafter described and claimed, the description beingsupplemented by the accompanying drawing.

Fig. 1 is a top plan view of a portion of a planter equipped with thecheckcorrecting means.

Fig. 2 is a vertical transverse section on line 2-2 of Fig. 1.

Figs. 3 and 4 are sectional views on the correspondingly numbered linesof Fig. 2. 1

In the drawing above briefly described, 5 denotes the main frame of theplanter, said frame having an axle 6 provided with supporting wheels 7at its ends, one of these wheels being loose upon the axle while theother is secured to it in the usual manner. The front end of the frame 5is connected to an auxiliary frame 8 provided with the usual seeddropping units such as 9. 10 do notes operating means for the units 9,constituting no part of the present invention and protected by theallowed application 'above referred to, and 11 denotes a driving chainfor said operating means 10.

The chain 11 is driven by a. sprocket wheel 12 which is loose upon theaxle 6. Two ratchet wheels 13 and 1a are disposed at opposite sides ofthe sprocket wheel 12 and have their teeth facing in the same direction,

said sprocket wheel being provided with pawls 15-16 co-operating withsaid teeth respectively. The ratchet wheel 14 is connected with the axle6 and in the present showing is formed with recesses 17 in its outerside receiving projections 18 on a collar 19, the latter being securedby a set screw or the like 20 to said axle. The ratchet wheel 13 issecured to a sleeve 21 which is free to rotate on the axle 6, and theconnect- Serial no. 208,367.

ing means between said wheel-13 and said? sleeve -may well consist-ofco-operable sockets and lugs Ti -18 The sleeve 21 passes rotatablythrough one of the bearings 22-of the axle 6 and is secured, forinstance, by set screws 23 to the hub 24: of the wheel 7 which is looseon said axle 6.

By providing the pawl and ratchet arrangement and associated features ofconstruction, it is insured that one or the other of the planter wheelsshall always drive the sprocket wheel 12, yet the necessary relativeturning of said wheel's when" the machine is turned around at the endsof rows, is permitted.

A lever 25 is loosely mounted at its lower end upon the sleeve 21,between the ratchet wheel '13 and a collar 26 on said sleeve, the upperend of said lever having a hand grip 27. A spring-raised rod 28 isslidable in the lever 24 and is provided at its lower end with a pawl 29for engagement when desired with teeth of the sprocket wheel 12, the rodand pawl however, being normally raised by means of a spring 30. At theupper end of the rod, a handle 31 is provided, said handle being locatedin a recess 32 in the hand grip 27. By depressing this handle from thedotted line position of Fig. 2 to the position shown in full lines inthis View, the pawl 29 v is positioned to engage the sprocket wheel 12.Then, the latter may be turned so as to drive the chain 11 for thepurpose of prop:- erly setting the seed dropping mechanism atthe'beginning of any row across the field, or for efiecting checkcorrection whenever necessary.

If desired, ball or roller bearings may be used at any or all points offriction and'it will further be understood that minor variations as todetails, may be made within the scope of the invention as claimed.

1 claim i 1. In a corn planter having a wheel driven axle provided atone end with a loose wheel; a sleeve rotatably surrounding a portion ofthe axle and secured to the loose wheel, a

loosely mounted on the axle between the two ratchet wheels for drivingseed-dropping wheel and engaging the ratchet wheels, a

mechanism, pawls carried by the sprocket lever mounted on said sleevefor free oscillation With respect thereto, and a projectible andretractible dog .on the lever for engagement With the sprocket Wheel forturningthe latter With respect to the ratchet Wheels.

2. In a corn planter having a Wheel driven axle provided at one end witha loose Wheel, a sleeve rotatably surrounding a. portion of the axle andsecured to said loose Wheel, a

planter-operating heel loose upon theaxle, o
